Security Door Handles - FAQ's

What is a security door handle?

Security door handles are a fairly recent innovation found in many residential door applications and largely the result of much publicity given to the burglary technique known as lock snapping. These door handles have been produced to achieve the 2 star rating for security as required by TS007.

How do these handles stop lock-snapping?

These upvc door handles have been designed in several ways to counteract access to the cylinder. The cylinder is the weakest part and if the door handle can be removed then it can be easy to snap the lock in the middle, and then use a tool to wind back the locks around the door for access. The manufacturer of these handles, Hoppe, have incorporated several important features within the design and most notably:

  1. Cylinder guard to cover the end of the cylinder.
  2. 15mm solid aluminium outer plate to stop the plate being broken.
  3. Chamfered edge to the design of the handle backplate to stop mole grips clamping to the handle.
  4. The use of 6mm diameter screws and a special hardened screw bolt to stop the handle being pulled off the door via the screws.

Why will the handles only fit 3 sizes of door thickness?

The pin bolt is made to a certain length to ensure sufficient thread is used to secure the handles to the door and this means the bolt size determines the door thickness. The 44mm, 60mm and 70mm door sizes are seen as the most popular. If there is more than a couple of millimetre difference to these sizes the security handles cannot be used.

My upvc door handles have different fixing centres and key-hole positions?

The security handles we show on the HandleStore website will only fit certain types of locks so check carefully the sizes you need via this upvc door handles checker. If your sizes are not the same as the security handles shown then you cannot use them.

Most upvc door handle manufacturers only produce handles for the latest and most standard size locks so many of the locks found in the replacement market will not be able to use security handles. In this case seek further advice on how to strengthen the lock cylinder from lock snapping and lock bumping and at least look towards a lock cylinder that will offer more protection.
